1. Qhov tseem ceeb rau kev cuam tshuam stamping kev ua tau zoo
(1) Khoom Siv Khoom
Paib lub zog: 355 MPa (min) - siab dua cov hlau me me, xav tau ntau dua stamping quab yuam.
Elongation (a5): ~ 22-26% (Raug rau S355J0WP) - Siv tau rau kev sib sau tab sis qis dua li cov hlau sib sib zog nqus.
Anisotropy (R-tus nqi): Nruab nrab (ferrite-hlaws microstructure tej zaum yuav ua rau tsis muaj kev sib luag).
(2) Cov Hluav Taws Xob Hlau Sib Tw
Tooj liab / phosphorus cov ntsiab lus: Txhim kho corrosion tsis kam tab sis tuaj yeem txo kev du sij hawm me ntsis.
Nto Rust Txheej Txheej: Pre-uas twb muaj lawm zeb nplai los yog patina tej zaum yuav nce cov kev hnav hnav thaum lub thwj.
2. Stamping haum
| Chaw ua uas tsis tau haus | S355J0WP Performance | Sib piv rau cov hlau me (piv txwv li, S235) |
|---|---|---|
| Muaj meej | Mob (haum rau khoov, cov nyom ntiav) | Cov hlau me me yog qhov zoo dua rau cov duab nyuaj |
| Caij nkoj nthuav dav | Siab dua (vim muaj zog) - yuav tsum tau overbending | Qis dua springback |
| Tuam Kev Hnav | Me ntsis nce (abrasive xeb txheej) | Tsawg hnav nrog cov chaw huv |
| Ntug kev txaus ntshai | Nruab nrab (tswj cov pam vov kev kom zoo zoo) | Tsawg txoj kev pheej hmoo |
3. Pom zoo cov kev coj ua
(1) cov txheej txheem ua kom zoo
Kev Npaj Dawb:
Tshem tawm mill nplai / xeb ntawmtxhaj koob tshuaj tiv thaiv blastinglossis pickling ua ntej stamping.
Siv lubricants (piv txwv li, phosphate txheej lossis roj) kom txo kev sib txhuam.
Tuam Tsim:
Siv cov cuab yeej hardened (piv txwv li, d2 lossis carbide) kom tawm tsam kev hnav.
Nce punch / tuag tshem tawm los ntawm10–15%vs me me hlau kom tsis txhob tawg.
XOVXWM NRES:
Siab tonnage yuav tsum tau (kwv yees:20-30% Ntau Forcetshaj S235).
Qeeb txuag ceev ceev los txo cov kev ntxhov siab hauv ib cheeb tsam.
(2) Kev txiav txim siab tshaj tawm rau kev sib tw
Kev ntxhov siab nyem: Kev siv kub tsawg-kev kub siab (yog tias kev ua haujlwm txias txias heev).
Corrosion tiv thaiv: Rov ua dua npe rau cov chaw rau huab cua kom hloov kho Patina tiv thaiv Patina.
4. Cov ntawv thov raug (stamped seem)
Panels(Yooj yim khoov, perforations).
Nkhaus thiab txhawb nqa(ntu kev nyuaj).
Tsheb thauj mus los hauv(piv txwv li, tsheb ciav hlau - yuav tsum muaj ntug kev tswj hwm zoo).
5. Lwm txoj hauv kev rau cov khoom sib tw
Rau kev sib sib zog nqus kos duab: Xav txog Softer Steels (piv txwv li, DC04) lossis cov huab cua txuas ntxiv ua hluav taws xob hlau.
Rau qhov siab precision: Laser txiav + khoov yuav outperform stamping rau qhov tseem ceeb ua kom muaj kev puas tsuaj loj.
6. Kuaj cov lus pom zoo
Coj kev sim khiavnrog cov khoom me me kom kho cov tsis yog.
Saib xyuas: Ntug tawg, cov cuab yeej hnav, thiab caij caij ntuj lub caij tsim khoom.
